Yes. PGT is best station in Kerala in terms of cleanliness and maintenance. The other day while i was returning from hometown in 12602. One of my co traveller was saying to his friend when train reached PGT, look at the station. This is the cleanest station in Kerala.
Ya one reason is, morning time, the time when people uses toilet max, comparatively less long distance train arrives. But yes, cleaning staff also need appreciation. They really maintain it well.. Have been in Palakkad for more than 23 yrs, and now after leaving from PGT, i realise how much attached i am to PGT Jn.
